Abstract
Room temperature continuous wave operation of CdZnSSe/ZnSSe quantum well laser diodes based on wide-gap II-VI semiconductors with lifetimes >3 h has been demonstrated. The density of stacking faults and threading dislocations present inside the laser diodes is ~5 × 104 /cm2. Laser emission was observed at a wavelength of ~529 nm with a threshold current density of ~460 A/cm2 and a threshold voltage of ~5 V in index-guided CdZnSSe/ZnSSe/MgZnSSe separate-confinement heterostructure laser diodes.Keywords
